The F-35 promised reach without rival, yet its heart – Pratt & Whitney’s F135 – burns fuel like an older design. Thrust-specific fuel consumption (TSFC) shows why. The F100-PW-229 that powers late-model F-15s and F-16s clocks 0.726 lb/hr/lb. The F135 sits at 0.889 lb/hr/lb, a 22 percent penalty that drags range and keeps tankers busy.

Pilots walk to their jets before sunrise, climb the ladder, key the INS, and watch the route and target files flow in by Link 16. A typical launch leaves the chocks with the following kit:

Lockheed Martin’s F-35 is America’s most expensive weapons project. After fifteen years in development, the jet is still not ready for the fight the services expect. A confidential memorandum dated Aug 9 from Dr. Michael Gilmore, the Defense Department’s Director of Operational Test and Evaluation, warns that the fighter “is not on a path toward success.” His language is blunt.

The B-2 Spirit edges into a new era. Air Force engineers push the bomber toward a fresh role—striking vehicles that refuse to sit still. The project looks dry on paper, yet it shifts how commanders think about fast raids. Crews on the flight line watch small changes pile up; each tweak nudges the jet away from its 1990s roots. 

Lockheed Martin reshaped a small yet vital slice of the F-35 frame. The fresh FS425 bulkhead now backs bigger bombs inside the jet. Crews hope the tweak keeps radar print low while packing harder punch. Work moved quick during late-2023 and spread wider this year.

The T406 engine reached a solid 500-hour record on one Osprey in mid-August last year. It happened during normal line ops, not a test flight. The count feels modest next to jetliner totals, yet inside tiltrotor work it signals tough stamina. Dust storms, salty deck spray, rough landings—each hop chews parts quicker than manuals predict.

The Indian Navy has fought hard to keep its carrier aviation alive after retiring the Sea Harrier. MiG-29K fighters now fill that hole on INS Vikramaditya and the soon-to-sail INS Vikrant. Admiral Sunil Lanba told reporters on the eve of Navy Day that the spares drought and maintenance snags dogging the fleet are “behind us for good.” He stressed that every outstanding invoice with Russian suppliers has a clear payment path despite U.S. sanctions.

The latest annual report from the Pentagon’s Director of Operational Test & Evaluation (DOT&E) states that the F-35 Joint Program Office (JPO) claimed improved reliability by adjusting the way it records equipment failures rather than by delivering technical corrections.
